Soda Peak Gummies L-Arginine, an amino acid that serves as a precursor to nitric oxide, has been studied for erectile dysfunction at doses between 1,500 and 5,000 milligrams per day; the 50 milligrams in the SodaPeak formula is a fraction of that amount . Beet root extract and grape seed extract have their own literatures, but again, the doses in the gummy are unlikely to match those used in research.
